thanks....I am inclined to mount it almost vertical inverted.heck lots of guys do it and experience no problem I think I worry too much about nothing.but I will make sure the fuel tank centerline is just below the carb.maybe no more than 1/2 inch..as for fuel dots...I used one with my funtana 40 and love the simplicity and ease of a fuel dot source.never knew much about them until I used one in my big stinger..works a bit easier with gas but very nice in glow engines as well. appreciate your help!
